1. Installation Hardware
1.1 System requirements for computer or laptop on the part of operator
Following system requirements are needed for installation parameterization software
on computers or laptops:
1. Windows 2000 (32 bit)
2. Windows XP (32 bit)
3. Windows Vista (32 bit)
4. Windows 7 (32 bit)
Internal clock: 600 MHz or faster
Main memory: 256 MB RAM or bigger
Hard disc with min. 512 MB or bigger
CD-ROM drive
Screen resolution: 1024 x 768
For computers, which operate with 64 bit, we would recommend to set the above-mentioned
systems on 32 bit via "virtual machine".
1.2 Application Area
The KHS Logic Control System provides a central interface for the automated flushing process of an entire
facility. It comprises a programmable control unit where the flushing programs are stored and which is
compatible with all KHS servomotors and sensors. The user can select the required operation mode in a targeted
manner by entering operation types such as time control, temperature control or volume flow control, while
parameterizing the flushing volumes or periods previously established via simulation within the KHS Logic.
1.3 Setup
The system is controlled via an SPC in the shape of a top hat rail PC. A further local computer (e.g. laptop or host
computer, if available) is required in order to parameterize the system using the parameterization software
included by executing freely selectable servomotor activation combinations with the sensors.
Special Safety Information
- The components may only be installed and taken into operation by qualified professionals familiar with
applicable national standards.
- The system in hand carries potentially harmful currents. These voltages can cause extensive damage to property
and serious to life-threatening injuries.
- The system operator is required to ensure that the system is only used as intended.
- The maximally permitted ambient temperature is 55°C.
- The switch case system delivered is protected in compliance with IP 55. If the switch case is subsequently
modified we are unable to accept any liability in terms of contact, foreign body and water protection.

1.4.1 Switch Case Exterior Buttons
Quick Stop
The quick stop button sets the system to a defined initial state (for example in case of damaged duct system).
This means that any flushing processes that may be in progress are discontinued and the servomotors are set to
their rest position (closed).
No new flushing processes will be started until the root cause of the fault has been eliminated and the system is
set to „Ready“ again. To this end the respective fault needs to be acknowledged in the parameterization
software (button „Fault Messages“, see Section 3.1.19). Only then will the system be ready for operation once
more and be able to perform all the parameterized flushing processes as desired.
Ready
Besides the function described above, the „Ready“ button is also needed to start the system once it has been
installed and taken into operation.
Manual
“Manual operations“ in the parameterization software (see Section 3.1.8ff) are signalled by the „Manual“ LED.
Automatic
Indicates the „Automatic“ operating mode. This is activated as soon as the operator deselects the “Manual”
operating mode in the parameterization software (see Setion 3.18).
Fault
The „Fault“ signal lights up permanently if one of the listed errors occurs in the system.
The following faults can occur:
- No valve feedback (opening)
- No valve feedback (closing)
- Canal flooding
- No B-valve assigned
- System in quick stop
- Safety fuse in switch case activated
-2-
The following table (Tab.:1 Fault Messages) describes the errors causing the activation and their respective
impact on the system. If only the group of the valve is closed, the other groups or individual valves will continue
operating. If the entire system is shut off, no further valve will be activated until the error to have occurred has
been eliminated and acknowledged.

Flushing in Progress
This LED is activated as soon as a flushing process occurs in the system, taking into account the A-valves
(servomotors open/close), C-valves (servomotors with spring reset) and hygiene flushing units. No new
transmission is possible from the parameterization software while a flushing process is active.
1.5 Hardware Components
The hardware components generally comprise a Rittal terminal box, a Beckhoff CX_9000 top hat rail PC and
several Beckhoff terminals. The KEMPER KHS Logic control system (Figure 686 02 001, Figure 686 02 002 and
Figure 686 02 003) is offered in flexible system sizes differentiated by the number of resources to be used. The
resources in this case include all the servomotors, temperature and throughput measurement fittings, overflow
protection devices and hygiene flushing units.

Example Servomotor Type A
Selecting the page of the respective canal. This is identified via the page title (see Ill. 1-3a) and servomotor
description field (see Ill. 1-3b). Both connection options, i.e. for type A servomotors, Fig. 68600, as well as the
servomotors with spring reset type B and C, Fig. 68601, are shown on the page of each valve (see Ill.1-3 d)). A
servomotor of the Fig. 68600 is used in our example (see Ill. 1-3 c). The servomotor needs to be connected as
indicated in the left image section or Table 2. This means that the blue (bl) and the red (rt) wire need to be
connected to a free series terminal designated as 24L-, and the brown (br) wire to a free 24L+ series terminal. In
our example the black wire (sw) needs to be connected to module terminal A231/1 (see Ill.1-3 e) and the grey
wire (gr) to module terminal A331/1 (see Ill: 1-3 f).

Pic. 1-3 Circuit Diagram Excerpt (Servomotor Type A V101)
Please make sure to check the terminal connections before the first start-up. If the valve channels, for example
A231/1 and A331/2, should be mixed up when connecting a servomotor, the control unit will fail to work
properly and the functioning of the hygiene system unit can not be guaranteed. Testing all the settings and
terminal connections in the “Manual” operating mode is hence recommended. Please see Section 3.1.8 for a
detailed description of the „Manual“ operating mode and the attendant parameterization window.

Example 2 Throughput Measurement Device
A permanently assigned channel also needs to be selected here, as was the case with the servomotors. Please use
channel D101. The channel assignment process is described in detail in Section 3.1.5. The channel designation
can be found in the page title of the circuit diagram (see Ill. 1-4a) or the description of channel D101 (see Ill. 14b).
The throughput measurement device needs to be connected as shown in Illustration 1-4 or in Table 3. This
means that the yellow (ge) wire needs to be connected to a series terminal designated as 5L+, the white (ws)
wire to a series terminal designated as 5L- and the green (gn) wire to module terminal A351/1.

window. As soon as the system is online and the hardware configuration has been transmitted, the valves will be
shown in different colours:
Grey valve closed yellow valve is opening
green valve open
The sensor values are displayed at the same time. To gain an overview of whether the electrical connection and
data acquisition have been performed properly, it is recommended to manually perform a so-called program run
and functional check, in order to ensure the proper functioning of the individual sensors and valves. For larger
objects it is hence recommended that this function check is performed by two people (e. g. using walkie-talkies).
- 28 -
3.1.7 Manual Operation A-Valves

3.1.17 Volume Data Acquisition for Time or Temperature Control
With a volume flow sensor connected, the respective discharge volume of a temperature- or time-dependent
flushing can be lodged in the flushing protocol. Go to the index tabs “B-Valves” or “C-Valves” and select the Bor C-valve to be configured. Then select the sensor in question, which is located immediately in front of the
flushing valve, in the “Volume Sensor” field. Confirm with “valve accept”, then go to “File” and select
“Transmit”.
3.1.18 Flushing Protocol
To download the flushing protocol from the control unit,
please go to the index tab „Flushing Protocol“ and select
„Download Protocol“. The download from the control unit
may take a few minutes, depending on the file size. Given
the maximum number of 50.000 entries (equalling 50.000
flushing processes), approximately 10 minutes will be
required until the file can be displayed and/or stored.
Display the flushing protocol in the program by clicking on
the “Display” button. Store the flushing data in an Excel file
by clicking the “Save in Excel” button.

3.1.19 Current Fault signals
Clicking on the index tab „Fault signals“ will display the current fault messages and the fault message archive.
The „Fault signals“ index tab will flash in red as soon as a malfunction occurs. To delete the fault, click on the
“Update” button.
3.1.20 Fault signals archive
Click the „Archives“ button in order to go to the fault signals archive, where all the faults to have occurred up to
this point in time are displayed. The faults are shown in red as soon as they have occurred and in yellow once
they have been acknowledged.

3.2 Temperature Monitoring
KHS temperature monitoring for hot potable water and potable water circulation monitors all the decisive
temperatures in the hot water grid. A maximum of 100 sensors can be lodged in the parameterization software.
This includes the storage of target values for every single temperature sensor.
You can provide hot water temperature sensors in the temperature monitoring program and hence record the
temperatures in the temperature protocol at defined monitoring times. To do this, click on “Start” and confirm
with “OK”.
3.3 Project Creation
Enter the project data in this window analogous to the KHS flushing unit start mask and click on the „Offline“
button in order to establish a software connection.

3.4 Hot Water Temperature Sensors
In the „Sensors“ tab index you can define the temperature sensors that are to be monitored later on. To do this,
please define the properties of the sensors:
The point where a thermal disinfection occurs.
The point where a target value is exceeded or fallen short of, with these excessive or short values being written
in the temperature protocol.
Please enter the sensor type in the “Sensor Type” field.
The “Monitoring Times” define the points in time when the temperatures are written to the temperature
protocol.
Please set the temperature sensors as follows:
Start by assigning an appropriate “Channel Number” and “Sensor Name” to the sensor number.
The following parameters need to be entered in the middle section (the default settings comply with
Worksheet W551 / W553 of the German gas and water association DVGW):
- Thermal disinfection (70 °C - 90 °C): Enter the minimum temperature to be reached for thermal disinfection
(default setting is 70 °C).
- Maximum target value (45 °C - 70 °C): Enter the reservoir output temperature. Temperatures exceeding
this target value will be recorded in the temperature protocol (preset to 60 °C).
- Minimum target value (40 °C - 65 °C): Enter the reservoir input temperature (circulation) (preset to 55 °C).
Temperature Sensor Creation Example
In the example shown above, a hot water temperature sensor has been established with the preset parameters:
Thermal disinfection at 70 °C
Maximum target value threshold at 60 °C
Minimum target value threshold at 55 °C
Sensor type: PT1000
The threshold values set here only serve to record the temperatures in the system! No flushing will be activated
in the hot water system!
You can furthermore establish monitoring times (6 times per day) for each sensor as described in Section 3.4 Hot
Water Temperature Sensors, at which points in time protocol entries will be performed subsequently.
